While the various features of this invention are hereinafter described and illustrated as being particularly adaptatble to provide substantially rectangular container constructions or the like, it is to be understood that the various features of this invention can be utilized singly or in any combination thereof to provide other types of container constructions or the like.

Therefore, this invention is not to be limi-ted to only the embodiment-s illustrated in the drawings, because the drawings are merely utilized to illustrate one of the wide variety of uses of this invetnion.

3,302,855 Patented Feb. 7, 1967 ICC Referring now to FIGURES l and 2, an improved container construction of this invention is generally indicated by the reference numeral 20 and can be formed "of cardboard, laminations and the like, the container construction 20 having opposed front wall means 21 and back wal-1 means 22, opposed end wall means 23 and 24 and opposed top wall means 25 and bottom wall means 26.

While the icontainer construction 20 of this invention can be formed in any suitable manner and of any suitable material, the container construction 20 can be formed from a cardboard container blank of this invention generally indicated by the reference numeral 27 in FIG- URE 5.

As illustrated in FIGURE 5, the container blank 27 is suitably cut and scored to ydefine a substantially rectangular :blank having the end wall means 24, back wall means 22, end wall means 23 and front wall means 21 serially dened :by transversely. disposed and parallel scores 28, 29 and 30. t

An interconnecting ap 31 is integrally interconnected to the front wall means 21 and is defined by a transversely disposed score 32.

A plurality of top flaps 33, 34, 35 and v36 are integrally interconnected to the top edges of thewall means 24, 22, 23 and 21 and are defined by a longitudinally disposed score 37, the top tiaps 33, 34, 35 and 36 being separated from each other by die cuts 37', 38 and 39.

Similarly, a plurality of bottom aps 4t), 41, 42 and 43 are integrally interconnected to the bottom edges of the wall means 24, 22,l 23 and 2l and are dened 'by a longitudinally disposed score 44, the bottom flaps 40, 41, 42 and 43 being separated from each other Iby die cuts 45, 46 and 47.

`When the blank 27 is folded into the rectangular container construction 20 illustrated in FIGURE 1, the aps 40 and 42 are first disposed over the bottom end thereof and the flaps 41 and 43 are then superimposed thereon in overlapping relation to form the bottom wall means 26 in a conventional manner.

However, the top Hap 34 of the blank 27 has an outwardly extending tongue 48 adapted to be receivable in a slot 49 die cut in the flap 36 to hold the top flaps 33, 34, 35 and 36 in the overlapping relation illustratedin FIGURES l and 2, the overlapping aps 34 and 36 forming the top wall means 25.

A pair of spaced, parallel and longitudinally disposed scores 50 and 51 extend across the blank 27 and divide the blank 27 into substantially equal portions, certain portions of the scores 50 and 51 comprising perforations in a manner now to be described.

As illustrated in FIGURE 5, the wall means 24 is divided into three sections 52, 53 and 54 by perforated portions 55 and 56 of the scores 50 and 51. The back wall means 22 is divided into three sections 57, 58 and 59 by the scores 50 and 51, the score 50 defining a perforated portion 60 disposed intermediate the outer edges of the back wall portion 58 for a purpose hereinafter described and being joined to angularly disposed perforations 61 and 62 joining the perforated portion 60 with the transversely disposed scores 28 and 29. t

The end wall means 23 is divided into three sub, stantially equal portions 63, 64 and 65 by perforated portions 66 and 67 of the scores 50 and 51. Similarly, the wall means 21 is divided into three substantially equal portions 68, 69 and 70 by perforated portions 71 and 72 of the scores 50 and 5I, the interconnecting flap 31 also being divided in substantially three equal portions 73, 74 and 75 by perforated portions 76 and 77 of the longitudinal scores 50 and 51.

The upper portion 57 of the back wall means 22 is dened in part by a perforatedportion 78 of the l-ongitudinal score 37, the perforated portion 78 being disposed short of the transverse scores 28 and 29 and being joined thereto by angularly disposed scores 79 and 80.

The portions 57 and 58 of the back wall means 22 are divided into two parts 81, 82 and 83 and 84 by respective scores 85 and 86.

The parts 81 and 82 of the back wall means 22 are separable from the portions 52 and 63 of the end wall means 24 and 23 by perforated portions 87 and 88 of the transverse scores 28 and 29. Similarly, the parts 83 and 84 of the back wall means 22 are separable from the portions 53 and 64 of the end wall means 24 and 23 by perforated portions 89 and 90 of the transverse scores 28 and 29.

After the blank 27 has been cut and scored in the manner illustrated in FIGURE 5, the same is adapted to form the container construction 20 illustrated in FIG- URE l by the folding of the blank 27 on the scores 28, 29, 30 and 32 so that the interconnecting ap 31 can be secured to the inside surface of the end wall means 24 whereby a substantially rectangular tubular structure is formed. Thereafter, the bottom wall means 26 can be formed from the bottom flaps 40, 41, 42 and 43 in the manner previously described whereby the desired product can be disposed through the open top end of the container construction 20. Thereafter, the container construction 20 can be closed by the top flap means 33, 34, 35 and 36 in the manner illustrated in FIGURE 1 to complete the container construction 20 of this invention.

If desired a disposable overwrap can be provided for the container construction 20.

When the ultimate consumer receives the package construction 20, the ultimate consumer can dispense the product packaged therein by opening the top ilaps 33-36. However, when the level of the product remaining in the package construction 20 falls below the longitudinal score 50 of the package construction 20, the package construction 20 can be reduced in the manner illustrated in FIGURE 3 by the ultimate consumer merely removing the top wallmeans 25 and upper portions 52, 63, 68 and 73 of the wall means 24, 23, 21 and interconnecting flap 31 along the perforated portions 55, 87, 79, 78, 80, 88, 66, 71 and 76 in the manner illustrated in FIGURE 3 wherein the upper portion 57 of the back wall means 22 extends above the remaining portions 53, 64, 69 and 74 of the wall means 24, 23, 21 and interconnecting flap 31. Thus, the reduced container construction 20 illustrated in FIGURE 3 can be subsequently closed for storage purposes thereof by folding the part 81 on the score 85 to provide a tuck-in flap while the part 82 is folded on the score 50 in the manner illustrated in FIGURE 4 to close the reduced container construction 20, the tuck-in part 81 having the corners thereof removed at the perforated parts 79 and 80 in the above manner to facilitate insertion of the tuck-in part 81 in the reduced container in the manner illustrated in FIG- URE 4.

After the product in the reduced container illustrated in FIGURES 3 and 4 has been dispensed therefrom so that the level of the product remaining in the reduced container 20 falls below the score 51, the container construction 20 can be further reduced by separating the now top wall means 57 and now upper portions 53, 64, 69 and 74 of the wall means 24, 23, 21 and interconnecting flap 31 along the perforated portions 56, 89, 61, 60, 62, 90, 67, 72 and 77 in the manner previously described whereby the remaining portion 58 of the back wall means 22 can provide the top wall means for the further reduced container construction 20 of this invention.

Therefore, it can be seen thatthe container construction 20 of this invention is adapted to have the same serially reduced so that the container construction 20 can have the size thereof conform to the level of product remaining therein whereby a minimum of storage space is required for the product remaining in the container construction 20.

While the container construction 20 is illustrated as having only two reducing portions thereof, it is to be understood that the container construction 20 of this invention could have one or any number of reducing portions formed therein in the manne-r illustrated in FIGURE 5 and previously described.

vAnother container construction of this invention is generally indicated `by the reference numeral 91 in FIG- URES 6 and 7 and is adapted to be reduced in size in a manner similar to the container construction 20 as the product level in the container construction 91 diminishes, the container construction 91 including a front wall means 92, rear wall means 93 opposed end wall means 94 and 95 and opposed top and bottom wall means 96 and 97.

While the container construction 91 of this invention can be formed in any suitable manner and of any suitable material, the embodiment thereof illustrated in the drawings is formed from a cardboard blank generally indicated by the reference numeral 98 in FIGURE 10 and suitably cut and scored in a manner to dene the wall means 94, 92, 95 and 93 by transversely disposed scores 99, 100, and 101.

An interconnecting iiap 102 is integrally interconnected to the back wall means 93 and is deined by a transversely disposed score line 104 for a purpose hereinafter described.

A plurality of top aps 105, 106, 107 and 108 are respectively interconnected to the top edges of the wall means 94, 92, 95 and 93 and are defined by a longitudinally disposed score 109, the flaps 105, 106, 107 and 108 being separated from each other lby die cuts `110, 111 and 112. The top flaps 10S-108 are adapted to be folded in the manner illustrated in FIGURE 6 to form the top wall means 96.

Similarly, a plurality of bottom aps 113, 114, 115 and 116 are integrally interconnected to the bottom edges of the wall means 94, 92, 95 and 93 and are defined by a. longitudinally disposed score 117, the bottom flaps 113- 116 being separated from each other by die cuts 118, 119 and 120. The bottom flaps 113-116 are adapted to 'be folded over in voverlapping relation in any suitable manner to deline the bottom wall means 97 of the container construction 91.

The wall means 94, 92, 95 and interconnecting flap 102 are respectively divided into three substantially equal portions by tear strip means 121 and 122 respectively defined by parallel spaced perforated lines 123, 124 and 125, 126.

In particular, the end wall means 494 is divided into three portions 127, 128 and 129 by the tear strips 121 and 122, the tear strips 121 and 122 having grasping end means 130 and 131 respectively formed Iby die cuts eX- tending to the free edge 132 of the wall means 94. Similarly, the tear strips 121 and 122 divide the front wall means 92 into three substantially equal portions 133, 134 and 135 while dividing the end wall means 95 into substantially three equal portions 136, 137 and 138. The interconnecting ap 102 is divided into three substantially equal portions 139, 140 and 141 by the -tear strip means 121 and 122 for a purpose hereinafter described.

The back wall means 93 of the Iblank 98 is divided into three substantially equal portions 142, 143 and 144 by parallel and spaced perforations 145 and 146 respectively aligned with the tear strip means 121 and 122.

The upper portion 142 of the back wall means 93 is separable from the top flap 108 by a perforated portion 147 of the longitudinal score 109 and is separable from the upper portions 136 and 139 of the end wall means 95 and interconnecting flap 102 by perforated portions 148 and 149 of the transverse scores 101 and 104.

The portion 143 of the back wall means 93 is separable from the portion 142 by the perforation 145 and is separable from the portions 137 and 140 of the end wall means 95 and interconnecting ap 102 by perforated portions 150 and 151 of the scores 101 and 104.

The portions 142 and 143 of the back wall means 93 are respectively divided into two parts 152, 153 and 154, 155 by scores 156 and 157 for a purpose hereinafter described.

After the blank 98 has been cut and scored in the manner illustrated in FIGURE and described above, the same is adapted to be folded into 4rectangular form on the score lines 99, 100, 101 and 104 whereby the interconnecting flap 139 is adapted to be interconnected to the inside surface of the end wall means 94. Thereafter, the bottom wall means 97 of the container construction 91 can be formed by first folding in the aps 113 and 115 and disposing the flaps 114 and 116 over the flaps 113 and 115 in overlapping relation and securing the same together in any suitable manner.

The product can then be disposed in the top end of the container construction 91 whereby the top of the container construction 91 can 4be closed by iirst folding in the flaps 105 and 107 and, thereafter, disposing the flaps 106 and 108 in overlapping relation in the manner illustrated in FIGURE 6.

When the ultimate consumer receives the container construction 91, the ultimate consumer can dispense the product therein by opening the top wall means 96. When the level of the product remaining in the container construction 91 falls below the tear strip 121, the ultimate consumer can grasp the end 130 of the tear strip 121 and tear the same from the container construction 91 whereby the portions 127, 133, 136 and 139 of the wall means 94, 92, 95 and interconnecting flap 102 will be separated from the remaining portions 128, 134, 137 and 140 thereof. Thereafter, the upper portion 142 of the back wall means 93 is separated from the top flap 108 and upper portions 136 and 139 of the end wall means 95 and interconnecting flap 102 at the perforated portions 147, 148 and 149 of the scores 109, 101 and 104 whereby the upper portion 142 of the back wall means 93 extends -above the portions 128, 134, 137 and 140 of the wall means 94, 92, 95 and interconnecting ap 102 in the manner illustrated in FIGURE 8.

The upper portion 142 `of the back wall means 93 then can be utilized to close the yo-pen end of the reduced container construction 91 by folding the part 152 on the score 156 to form a tuck-in flap while the other part 153 thereof extends |across the open end of the reduced container in the manner illustrated in FIGURE 9 to close the reduced container whereby the reduced container 91 is of `a size corresponding to the product remaining therein.

Thus, when the level of the product in the reduced container falls below the tear strip 122, the container construction 91 can y'be reduced in the manner previously described by utilizing the tear strip 122. and separating the par-t 143 of the back wall means 93 from the part 142 thereof 'along the perforation line 145 whereby the container construction 91 can be further reduced.

Therefore, it 4can be seen that this invention not only provides improved container constructions wherein the size of the container construction can be readily reduced as the product level therein decreases so that the container construction will substantially conform to the product remaining therein, but 'also this invention provides improved container blanks for forming such a container construction or the like.
